Dear Fellow Stockholder:
You are cordially invited to attend the 2019 Annual Meeting of Stockholders, or Annual Meeting, of Spark Therapeutics, Inc., or the Company or Spark.

Details regarding attendance at the meeting and the business to be conducted are more fully described in the accompanying Notice of Annual Meeting and Proxy Statement.
At the Annual Meeting, the agenda includes the election of three (3) Class I directors for a three (3) year term, the approval, by non-binding vote, of named executive officer executive compensation, and the ratification of the appointment of KPMG LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2019.
Under Securities and Exchange Commission rules, the Company is providing access to the proxy materials for the Annual Meeting via the Internet. Accordingly, you can access the proxy materials and vote at www.proxyvote.com. Instructions for accessing the proxy materials and voting are described below and in the Notice of Annual Meeting that you received in the mail. Your vote is very important. Whether or not you plan to attend the meeting, please carefully review the enclosed proxy statement and then cast your vote, regardless of the number of shares you hold. If you are a stockholder of record, you may vote over the Internet, by telephone or, if you request to receive a printed set of the proxy materials, by completing, signing, dating and mailing the accompanying proxy card in the return envelope. Submitting your vote via the Internet or by telephone or proxy card will not affect your right to vote in person if you decide to attend the Annual Meeting. If your shares are held in street name (held for your account by a broker or other nominee), you will receive instructions from your broker or other nominee explaining how to vote your shares and you will have the option to cast your vote by telephone or over the Internet if your voting instruction form from your broker or nominee includes instructions and a toll-free telephone number or Internet website to do so. In any event, to be sure that your vote will be received in time, please cast your vote by your choice of available means at your earliest convenience.

PROXY STATEMENT
FOR THE 2019 ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON SEPTEMBER 5, 2019
AT 8:00 AM EDT

INFORMATION ABOUT THE ANNUAL MEETING AND VOTING
When are this proxy statement and the accompanying materials scheduled to be sent to stockholders?
We have elected to provide access to our proxy materials for the Annual Meeting to our stockholders via the Internet. Accordingly, on or about July 22, 2019, we will begin mailing a Notice of Internet Availability of Proxy Materials, or Notice of Internet Availability, and all other proxy materials, including the Notice of 2019 Annual Meeting of Stockholders, this proxy statement and accompanying proxy card. For shares held in street name (held for your account by a broker or other nominee), a voting instruction form and the Annual Report on Form 10-K for the fiscal year ended December 31, 2018 will be made available to stockholders on the Internet on the same date.
Why did I receive a Notice of Internet Availability instead of a full set of proxy materials?
Pursuant to rules adopted by the U.S. Securities and Exchange Commission, or SEC, we are providing access to our proxy materials over the Internet rather than printing and mailing the proxy materials. We believe electronic delivery will expedite the receipt of materials and will help lower our costs and reduce the environmental impact of our Annual Meeting materials. Therefore, a Notice of Internet Availability will be mailed to holders of record and beneficial owners of our common stock starting on or around July 22, 2019. The Notice of Internet Availability will provide instructions as to how stockholders may access and review the proxy materials, including the Notice of Annual Meeting, proxy statement, proxy card and Annual Report on Form 10-K, on the website referred to in the Notice of Internet Availability or, alternatively, how to request that a copy of the proxy materials, including a proxy card, be sent to them by mail. The Notice of Internet Availability also will provide voting instructions. In addition, stockholders of record may request to receive the proxy materials in printed form by mail or electronically by e-mail on an ongoing basis for future stockholder meetings. Please note that while our proxy materials are available at the website referenced in the Notice of Internet Availability, and our Notice of Annual Meeting, proxy statement and Annual Report on Form 10-K are available on our website, no other information contained on either website is incorporated by reference in, or considered to be a part of, this document.
Who is soliciting my vote?
The Board of Directors of Spark, or the Board, is soliciting your vote for the Annual Meeting.
When is the record date for the Annual Meeting?
The Board has fixed the record date for the Annual Meeting as of the close of business on July 16, 2019.
How many votes can be cast by all stockholders?
A total of 38,895,341 shares of common stock of the Company were outstanding on July 16, 2019, and entitled to be voted at the Annual Meeting. Each share of common stock is entitled to one vote on each matter.

How do I vote?
If you are a stockholder of record and your shares are registered directly in your name, you may vote:
By Internet. Access the website of the Company’s tabulator, Broadridge, at: www.proxyvote.com, using the voter control number printed on the furnished proxy card. Your shares will be voted in accordance with your instructions. You must specify how you want your shares voted or your Internet vote cannot be completed and you will receive an error message. If you vote on the Internet, you also may request electronic delivery of future proxy materials.

1



By Telephone. Call 1-800-690-6903 toll-free from the U.S., U.S. territories and Canada and follow the instructions on the enclosed proxy card. Your shares will be voted in accordance with your instructions. You must specify how you want your shares voted or your telephone vote cannot be completed.
By Mail.  If you request printed proxy materials, complete and mail a proxy card in the postage prepaid envelope provided with such materials to Broadridge. Your proxy will be voted in accordance with your instructions. If you sign and return the enclosed proxy but do not specify how you want your shares voted, they will be voted FOR the election of the Class I director nominees named herein to the Board, FOR the advisory resolution approving the compensation of the named executive officers and FOR the ratification of KPMG LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2019, and will be voted according to the discretion of the proxy holder upon any other business that may properly be brought before the meeting and at all adjournments and postponements thereof. If you are mailed or otherwise receive or obtain a proxy card, and you choose to vote by telephone or by Internet, you do not have to return your proxy card.
In Person at the Meeting. If you attend the meeting, be sure to bring a form of personal picture identification with you, and you may deliver your completed proxy card in person, or you may vote by completing a ballot, which will be available at the meeting.
Telephone and Internet voting for stockholders of record will be available until 11:59 p.m. EDT the day before the Annual Meeting, and mailed proxy cards must be received by the day before the Annual Meeting to be counted. If the Annual Meeting is adjourned or postponed, these deadlines may be extended.
If your shares of common stock are held in street name (held for your account by a broker or other nominee), you may vote:
By Internet or By Telephone. You will receive instructions or a voting instruction form from your broker or other nominee if you are permitted to vote by Internet or telephone.
By Mail. You will receive instructions from your broker or other nominee explaining how to vote your shares.
In Person at the Meeting. If you attend the meeting, in addition to picture identification you should bring both an account statement or a letter from the record holder indicating that you owned the shares as of the record date, and contact the broker or other nominee who holds your shares to obtain a broker’s proxy card and bring it with you to the meeting.
What are the Board’s recommendations on how to vote my shares?
The Board recommends a vote:
Proposal 1: FOR the election of the three Class I director nominees
Proposal 2: FOR the advisory (non-binding) resolution approving the compensation of the Company's named executive officers
Proposal 3: FOR the ratification of the selection of KPMG LLP as the Company’s independent registered public accounting firm
Who pays the cost for soliciting proxies?
The Company will pay the cost for the solicitation of proxies by the Board.
The solicitation of proxies will be made primarily by mail and through Internet access to materials. Proxies also may be solicited personally, by telephone, fax or e-mail by employees of the Company without any remuneration to such individuals other than their regular compensation. The Company also will reimburse brokers, banks, custodians, other nominees and fiduciaries for forwarding these materials to their principals to obtain the authorization for the execution of proxies.
How are proxies voted?
All shares represented by valid proxies received prior to the applicable deadlines will be voted and, where a stockholder specifies by means of the proxy a choice with respect to any matter to be acted upon, the shares will be voted in accordance with the stockholder's instructions. However, if no choice is specified on a proxy as to one or more of the proposals, the proxy will be voted in accordance with the Board's recommendations on such proposals as set forth in this proxy statement.

2



Can I change my vote?
After you have submitted your proxy, you may still change your vote and revoke your proxy prior to the Annual Meeting by taking any one of the following actions:
submitting a new proxy by following the “Vote by Internet” or “Vote by Phone” instructions on the enclosed proxy card up until 11:59 p.m., EDT, the day before the Annual Meeting;
signing another proxy card and either arranging for delivery of that proxy card by mail prior to the start of the Annual Meeting or by delivering that signed proxy card in person at the Annual Meeting;
giving our Secretary a written notice before or at the Annual Meeting that you want to revoke your proxy; or
voting in person at the Annual Meeting.
Your attendance at the Annual Meeting alone will not revoke your proxy. If the shares you own are held in “street name” by a bank, broker or other nominee record holder, which we collectively refer to in this proxy statement as “brokerage firms”, your brokerage firm, as the record holder of your shares, is required to vote your shares according to your instructions and you must contact your brokerage firm for instructions as to how to change your vote.
Could other matters be decided at the Annual Meeting?
The Company does not know of any other matters that may be presented for action at the Annual Meeting. Should any other business come before the meeting, the persons named on the enclosed proxy will have discretionary authority to vote the shares represented by such proxies in accordance with their best judgment. If you hold shares through a broker, bank or other nominee as described above, they will not be able to vote your shares on any other business that comes before the Annual Meeting unless they receive instructions from you with respect to such matter.
What happens if the meeting is postponed or adjourned?
Your proxy may be voted at the postponed or adjourned meeting. You will still be able to change your proxy as outlined above under “Can I change my vote?”.
How can I find out the results of the voting at the Annual Meeting?
Preliminary voting results will be announced at the Annual Meeting. Final voting results will be published in a Current Report on Form 8-K, that we will file with the SEC within four business days after the Annual Meeting.
What does it mean if I receive more than one proxy card or voting instruction form?
It means that you have multiple accounts at the transfer agent or with brokers. Please complete and return all proxy cards or voting instruction forms to ensure that all of your shares are voted.
Who should I call if I have any additional questions?
If you hold your shares directly, please call Joseph W. La Barge, Secretary of the Company, at (855) 772-7589. If your shares are held in street name, please call the telephone number provided on your voting instruction form or contact your broker or nominee holder directly.
VOTES REQUIRED
How is a quorum reached?
The presence, in person or by proxy, of holders of at least a majority of the total number of outstanding shares entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting. Shares held of record by stockholders or brokers, banks or other nominees who do not return a signed and dated proxy or attend the Annual Meeting in person will not be considered present or represented at the Annual Meeting and will not be counted in determining the presence of a quorum. Abstentions and “broker non-votes”, if any, will be counted for purposes of determining whether a quorum is present for the transaction of business at the meeting. Broker non-votes occur when your broker or other nominee submits a proxy for your shares (because the broker or nominee has received instructions from you on one or more proposals, but not all, or has not received instructions from you but is entitled to vote on a particular "discretionary" matter) but does not indicate a vote for a particular proposal because the broker or other nominee does not have the authority to vote on that proposal and has not received voting instructions from you or has discretionary authority but chooses not to exercise it. If a quorum is not present, the meeting may be adjourned until a quorum is obtained.

3




How is the vote counted?
Votes cast by proxy or in person at the Annual Meeting will be counted by the persons appointed by Spark to act as tabulators for the meeting. The tabulators will count all votes “FOR”, “AGAINST” or to “WITHHOLD”, as well as abstentions and broker non-votes, as applicable, for each matter to be voted on at the Annual Meeting. Shares represented by proxies that withhold authority to vote for a nominee for election as a director will not be counted as votes “for” a director. Shares properly voted to “abstain” on a particular matter and broker non-votes are treated as having not voted on the particular matter and will therefore not affect the outcome of the proposals below.
Under the rules that govern brokers holding shares for their customers, brokers who do not receive voting instructions from their customers have the discretion to vote uninstructed shares on routine matters, but do not have discretion to vote such uninstructed shares on non-routine matters. Only Proposal 3, the ratification of the selection of KPMG LLP, is considered a routine matter where brokers are permitted to vote shares held by them without instruction. If your shares are held through a broker, those shares will not be voted in the election of directors unless you affirmatively provide the broker instructions on how to vote.
What vote is required to approve each item?
Votes cast by proxy or in person at the Annual Meeting will be counted by the persons appointed by the Company to act as tabulators for the meeting. The tabulators will count all votes “FOR”, “AGAINST” and to “WITHHOLD” abstentions and broker non-votes, as applicable, for each matter to be voted on at the Annual Meeting. Abstentions and broker non-votes are not counted as votes cast and, therefore, do not have the effect of votes in opposition to such proposals. A broker non-vote occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from a the beneficial owner.
Proposal 1 - Election of three Class I director nominees
The three nominees for election as Class I directors who receive the highest number of the votes cast (called a plurality) for election of directors shall be elected directors. Proposal 1 is a non-routine matter.
Proposal 2 - Advisory vote on executive compensation
To approve the advisory vote on the compensation of our named executive officers, a majority of the votes cast must vote FOR the proposal. Shares that abstain and broker non-votes will not be counted as votes in favor of this proposal and also will not be counted as votes cast. Only FOR and AGAINST votes will affect the outcome. Accordingly, abstentions and broker non-votes will have no effect on the voting of Proposal 2. Proposal 2 is non-binding. Because the vote is advisory and non-binding on us or our Board in any way, our Board may decide that it is in our stockholders' best interests to compensate our named executive officers in an amount and in a manner that differs from that which is approved by our stockholders. Proposal 2 is a non-routine matter.
Proposal 3 - Ratification of selection of KPMG LLP as our independent registered public accounting firm
To approve Proposal 3, holders of a majority of votes cast must vote FOR the ratification of the selection of KPMG LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2019. Proposal 3 is a routine matter.

PENDING ACQUISITION BY ROCHE HOLDINGS, INC.
On February 22, 2019, we entered into a definitive merger agreement to be acquired by Roche Holdings, Inc., or Roche, that provides for Roche to acquire Spark following the completion of a tender offer, or the Offer, and merger. Consummation of the Offer is subject to, among other customary conditions, regulatory approvals and customary closing conditions, including the expiration or termination of the applicable waiting period (or any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or the HSR Act. On June 7, 2019, each of Roche and Spark received a Request for Additional Information and Documentary Material, or a Second Request, with respect to the Offer from the Federal Trade Commission, or the FTC. The UK Competition and Markets Authority, or the CMA, has opened an investigation in order to obtain further information in relation to Roche's acquisition pursuant to the Offer and the merger. The investigation will determine whether the CMA considers that it has jurisdiction over the acquisition and, if so, whether the CMA considers that the acquisition may be expected to result in a substantial lessening of competition in the UK such as to warrant a more detailed Phase 2 review. Pending the outcome of its investigation, the CMA has issued an Interim Enforcement Order that would

4



become effective upon closing of the transaction and would require Roche to hold separate the Company's business. The parties are working cooperatively with the CMA and will continue to do so. On July 5, 2019, we entered into Amendment No. 1 to the merger agreement, or Amendment No. 1, with Roche and its acquisition subsidiary. Under the terms of the merger agreement prior to the amendment, December 31, 2019 is the date upon which, subject to the terms of the merger agreement, either we or Roche would have the right to terminate the merger agreement if the Offer has not been consummated on or before such date (the "end date"), provided that if on such date certain regulatory conditions (with respect to antitrust laws) have not been satisfied, either we or Roche may extend the end date to January 31, 2020 (the "extended end date"). Pursuant to Amendment No. 1, we and Roche have agreed to extend the extended end date to April 30, 2020 in order to provide the parties with additional time to satisfy those regulatory conditions (with respect to antitrust laws) in the event that additional time is necessary. The Company does not believe that the consummation of the Offer will result in a violation of any applicable U.S. antitrust laws. Roche and the Company continue to work cooperatively and expeditiously with the FTC in connection with its review. The Company and Roche continue to expect the transaction to be completed in 2019, and in the event that the transaction closes in advance of the scheduled Annual Meeting on September 5, 2019, the Company may cancel the meeting.

PROPOSAL 1: ELECTION OF CLASS I DIRECTORS
In accordance with Delaware law and the Company’s Restated Certificate of Incorporation and Amended and Restated By-laws, the Board is divided into three classes of approximately equal size, with members of each class serving staggered three year terms. Anand Mehra, M.D., Robert J. Perez and Lota Zoth, are the directors whose terms expire at this Annual Meeting and each of Dr. Mehra, Mr. Perez and Ms. Zoth has been nominated for and has agreed to stand for re-election to the Board to serve as a Class I director of the Company. Pursuant to the By-laws, the Board has fixed the number of directors at nine (9) as of the date of the Annual Meeting.
It is intended that, unless you give contrary instructions, shares represented by proxies solicited by the Board will be voted for the election of the three nominees listed below as director nominees. The vote of a plurality of the votes cast at the meeting will be required for the election of the Class I director nominees. Broker non-votes and votes withheld will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the election. The Company has no reason to believe that any nominee will be unavailable for election at the Annual Meeting. In the event that one or more nominees is unexpectedly not available to serve, proxies may be voted for another person nominated as a substitute by the Board, or the Board may reduce the number of directors to be elected at the Annual Meeting. Information relating to each nominee for election as director and for each continuing director, including his or her period of service as a director of the Company, principal occupation and other biographical material is shown under the heading "Director Biographies".
THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE
FOR
EACH OF THESE NOMINEES FOR CLASS I DIRECTOR
(PROPOSAL 1 ON YOUR PROXY CARD)

HOW OUR BOARD IS ORGANIZED
Composition of the Board of Directors
Our Board currently is authorized to have nine members and is divided into three classes, Class I, Class II and Class III, with members of each class serving staggered three-year terms. The members of the classes are as follows:
 
the Class I directors are Dr. Mehra, Mr. Perez and Ms. Zoth and their terms expire at the 2019 Annual Meeting;
the Class II directors are Drs. Altschuler, Ekman and High and their terms expire at the annual meeting of stockholders to be held in 2020; and
the Class III directors are Messrs. Marrazzo and Milano and Dr. Sigal and their terms expire at the annual meeting of stockholders to be held in 2021.
Upon the expiration of the term of a class of directors, directors in that class are eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires. In accordance with the terms of our Restated Certificate of Incorporation and Amended and Restated By-laws, our directors may be removed only for cause by the affirmative vote of the holders of at least 75% of the votes that all our stockholders would be entitled to cast in an annual election of directors.

DIRECTOR BIOGRAPHIES
The following table sets forth information concerning each member of our Board as of July 16, 2019. The biographical description of each director includes the specific experience, qualifications, attributes and skills that the Board would expect to consider if it were making a conclusion currently as to whether such person should serve as a director. In addition to the specific qualifications enumerated in their biographies, we believe that each of our directors possesses the attributes and characteristics described below under the heading “Board Processes - Minimum qualifications”.

DIRECTOR INDEPENDENCE
Rule 5605 of the NASDAQ Listing Rules requires a majority of a listed company’s board of directors to be comprised of independent directors within one year of listing. In addition, the NASDAQ Listing Rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent and that audit committee members also satisfy independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act.
Under Rule 5605(a)(2) of the NASDAQ Listing Rules, a director will only qualify as an “independent director” if, in the opinion of our Board, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries; or (2) be an affiliated person of the listed company or any of its subsidiaries. In addition, in affirmatively determining the independence of any director who will serve on a company’s compensation committee, Rule 10C-1 under the Exchange Act requires that a company’s board of directors consider all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: (1) the source of compensation of the director, including any consulting, advisory or other compensatory fee paid by such company to the director; and (2) whether the director is affiliated with the company or any of its subsidiaries or affiliates.
In April 2019, our Board undertook a review of the composition of our Board and its committees and the independence of each director. Based upon information requested from, and provided by, each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that each of our directors, with the exception of Mr. Marrazzo and Dr. High, is an “independent director” as defined under Rule 5605(a)(2) of the NASDAQ Listing Rules. Our Board also determined that Ms. Zoth and Drs. Altschuler and Ekman, who comprise our Audit Committee, Messrs. Milano and Perez and Dr. Altschuler and Ms. Zoth, who comprise our Compensation Committee, and Drs. Ekman, Altschuler and Sigal and Mr. Perez, who comprise our Nominating and Corporate Governance Committee, satisfy the independence standards for such committees established by the SEC and the NASDAQ Listing Rules, as applicable. In making such determinations, our Board considered the relationships that each such non-employee director has with our Company and all other facts and circumstances our Board deemed relevant in determining independence, including the beneficial ownership of our capital stock by each non-employee director.
There are no family relationships among any of our directors or executive officers.

BOARD COMMITTEES
Our Board has established four standing committees: Audit, Compensation, Nominating and Corporate Governance and Science and Technology, each of which operates under a charter that has been approved by our Board. Each such charter is available on the Investor Relations section of our website at www.sparktx.com.

Audit Committee
The members of our Audit Committee are Ms. Zoth and Drs. Altschuler and Ekman. Ms. Zoth is the chair of the Audit Committee. During the fiscal year ended December 31, 2018, the Audit Committee met five times. The report of the Audit Committee is included in this Proxy Statement under the heading “Audit Committee Report”. Our Audit Committee's responsibilities include:
 
appointing, approving the compensation of and assessing the independence of our independent registered public accounting firm;
overseeing the work of our independent registered public accounting firm, including through the receipt and consideration of reports from such firm;
reviewing and discussing with management and the independent registered public accounting firm our annual and quarterly financial statements and related disclosures;
monitoring our internal control over financial reporting, disclosure controls and procedures and code of business conduct and ethics, including the Company compliance hotline;
assessing our risk management policies;
establishing policies regarding hiring employees from the independent registered public accounting firm;
procedures for the receipt and retention of accounting related complaints and concerns;
meeting independently with our independent registered public accounting firm, management and internal auditing staff, if any;
reviewing and approving or ratifying any related-person transactions; and
preparing the Audit Committee report required by SEC rules.
All audit and non-audit services to be provided to us by our independent registered public accounting firm must be approved in advance by our Audit Committee.
Our Board has determined that Ms. Zoth is an “audit committee financial expert” as defined by applicable SEC rules. We believe that the composition of our Audit Committee meets the requirements for independence under the current NASDAQ Listing Rules and SEC rules and regulations.
Compensation Committee
The members of our Compensation Committee are Messrs. Milano and Perez, Dr. Altschuler and Ms. Zoth. Mr. Milano is the chair of the Compensation Committee. During the fiscal year ended December 31, 2018, the Compensation Committee met five times. Our Compensation Committee’s responsibilities include:
 
annually reviewing and approving corporate goals and objectives relevant to compensation for the Chief Executive Officer and our other executive officers;
determining our Chief Executive Officer's compensation as well as the compensation of our other executive officers;
overseeing an evaluation of our senior executives;
overseeing and administering our cash and equity incentive plans;
reviewing and making recommendations to our Board with respect to director compensation;
reviewing and discussing annually with management our “Compensation Discussion and Analysis”; and
preparing the annual Compensation Committee report required by SEC rules.
Our executive compensation program is administered by the Compensation Committee of our Board, subject to the oversight and approval of our full Board. Our Compensation Committee reviews our executive compensation practices on an annual basis and based on this review approves or, as appropriate, makes recommendations to our Board for approval of our executive compensation program. Our Chief Executive Officer recommends annual executive salary increases, annual equity awards and bonuses, if any, for the other executive officers, which are then reviewed and approved or adjusted by the Compensation Committee.
In designing our executive compensation program, our Compensation Committee considers publicly available compensation data for national and regional companies in the biotechnology/pharmaceutical industry to help guide its executive compensation decisions at the time of hiring and for subsequent adjustments in compensation. In 2017, our Compensation Committee engaged Willis Towers Watson as its independent compensation consultant to provide comparative data on

11



executive compensation practices in our industry and to advise on our executive compensation program generally. The Compensation Committee also engaged Willis Towers Watson for recommendations and review of non-employee director compensation in 2018. Although our Compensation Committee considers the advice and recommendations of Willis Towers Watson as to our executive compensation program, our Compensation Committee ultimately makes their own decisions about these matters. In the future, we expect that our Compensation Committee will continue to engage independent compensation consultants to provide additional guidance on our executive compensation programs and to conduct further competitive benchmarking against a peer group of publicly traded companies.
In April 2018, the Compensation Committee reviewed information regarding the independence and potential conflicts of interest of Willis Towers Watson, taking into account, among other things, the factors set forth in the NASDAQ listing standards. Based on such review, the committee concluded that the engagement of Willis Towers Watson did not raise any conflict of interest.

Our director compensation program is administered by our Board with the assistance of the Compensation Committee. The Compensation Committee conducts an annual review of director compensation and makes recommendations to the Board with respect thereto.

Nominating and Corporate Governance Committee
The members of our Nominating and Corporate Governance Committee are Drs. Ekman, Altschuler and Sigal and Mr. Perez. Dr. Ekman is the chair of the Nominating and Corporate Governance Committee. During the fiscal year ended December 31, 2018, the Nominating and Corporate Governance Committee met five times. Our Nominating and Corporate Governance Committee’s responsibilities include:
 
identifying individuals qualified to become board members;
recommending to our Board the persons to be nominated for election as directors and to each of the Board’s committees;
reviewing and making recommendations to our Board with respect to management succession planning;
developing and recommending to our Board corporate governance principles; and
overseeing periodic evaluations of our Board.
Science and Technology Committee
The members of our Science and Technology Committee are Drs. Sigal, Ekman and Mehra. Dr. Sigal is the chair of the Science and Technology Committee. During the fiscal year ended December 31, 2018, the Science and Technology Committee met five times. Our Science and Technology Committee’s responsibilities include:
reviewing, evaluating and advising our Board and management regarding the long-term strategic goals and objectives and the quality and direction of our research and development programs;
monitoring and evaluating trends in research and development, and recommending to our Board and management emerging technologies for building our technological strength;
recommending approaches to acquiring and maintaining technology positions;
advising our Board and management on the scientific aspects of business development transactions; and
regularly reviewing our research and development pipeline.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
Dr. Altschuler, Messrs. Milano and Perez and Ms. Zoth served as members of the Compensation Committee during the year ended December 31, 2018. None of our executive officers serves as a director or a member of a Compensation Committee (or other committee serving an equivalent function) of any other entity that has one or more of its executive officers serving as a director or member of our Compensation Committee. None of the members of our current Compensation Committee or our Compensation Committee for the year ended December 31, 2018, is, or has ever been, an officer or employee of our Company.

BOARD MEETINGS AND ATTENDANCE
Our Board held eleven meetings during the fiscal year ended December 31, 2018. Each of the directors attended at least 75% of the meetings of the Board and the committees of the Board on which he or she served during the fiscal year ended December 31, 2018 (in each case, which were held during the period for which he or she was a director and/or a member of the applicable committee). Although the Company has no formal policy about director attendance at annual meetings of stockholders, the

12



Company encourages its directors to attend the Annual Meeting of Stockholders. All members of the Board attended the Company's 2018 Annual Meeting of Stockholders.
As required under applicable NASDAQ listing standards, the Company's independent directors met at least twice in regularly scheduled executive sessions at which only independent directors are present in the fiscal year ended December 31, 2018.

BOARD PROCESSES
Identifying and evaluating director nominees
Our Nominating and Corporate Governance Committee focuses on board composition and succession planning on a continuous basis, with the expectation that other members of the Board, and of management, will be requested to take part in the process as appropriate. The Nominating and Corporate Governance Committee recruits and recommends nominees for election to the full Board, with the goal of creating a well-rounded Board that is able to provide effective oversight through an appropriate balance of skill sets, perspectives, diversity of experience, and other qualifications.
Generally, our Nominating and Corporate Governance Committee identifies candidates for director nominees in consultation with management, through the use of search firms or other advisors, through the recommendations submitted by stockholders or through such other methods as the Nominating and Corporate Governance Committee deems to be helpful to identify candidates. Once candidates have been identified, our Nominating and Corporate Governance Committee confirms that the candidates meet all of the minimum qualifications for director nominees established by the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee may gather information about the candidates through interviews, detailed questionnaires, background checks or any other means that the Nominating and Corporate Governance Committee deems to be appropriate in the evaluation process. The Nominating and Corporate Governance Committee then meets to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our Board. Based on the results of the evaluation process, the Nominating and Corporate Governance Committee recommends candidates for the Board’s approval as director nominees for election to the Board.
Minimum qualifications
Our Nominating and Corporate Governance Committee will consider, among other things, the following qualifications, skills and attributes when recommending candidates for the Board’s selection as nominees for the Board and as candidates for appointment to the Board’s committees. As basic qualifications, nominees for the Board must:
Adhere to the highest standards of personal and professional integrity;
Demonstrate exceptional ability and judgment; and
Effectively serve, in conjunction with the other nominees to the Board, the long-term interests of the stockholders.
In evaluating proposed director candidates, our Nominating and Corporate Governance Committee may consider, in addition to the minimum qualifications and other criteria for Board membership approved by the Board from time to time, all facts and circumstances that it deems appropriate or advisable, including, among other things, diversity (including, but not limited to race, gender or national origin), the skills of the proposed director candidate, his or her depth and breadth of professional experience or other background characteristics, his or her independence and the needs of the Board. We have no formal policy regarding Board diversity, however our Nominating and Corporate Governance Committee considers diversity when evaluating potential new directors. Our Nominating and Corporate Governance Committee’s priority in selecting Board members is identification of persons who will further the interests of our Company through his or her established record of professional accomplishment, the ability to contribute positively to the collaborative culture among Board members, and professional and personal experiences and expertise relevant to our growth strategy. The Nominating and Corporate Governance Committee will consider candidates recommended by stockholders. The policy adopted by the Nominating and Corporate Governance Committee provides that candidates recommended by stockholders are given appropriate consideration in the same manner as other candidates.
Board leadership and the role in risk oversight
Our Board currently is chaired by Dr. Altschuler. As a general policy, our Board believes that separation of the positions of Chief Executive Officer and chairman reinforces the independence of the Board from management, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of the Board as a whole. As such, Mr. Marrazzo serves as our Chief Executive Officer while Dr. Altschuler serves as our Chairman of the Board but is not an executive officer.

13



Our Board oversees the management of risks inherent in the operation of our business and the implementation of our business strategies. Our Board performs this oversight role by using several different levels of review. In connection with its reviews of the operations and corporate functions of the Company, our Board addresses the primary risks associated with those operations and corporate functions. In addition, our Board reviews the risks associated with the Company’s business strategies periodically throughout the year as part of its consideration of undertaking any such business strategies.
Each committee of our Board also oversees the management of the Company’s risk that falls within the committee’s areas of responsibility. In performing this function, each committee has full access to management, as well as the ability to engage advisors. Our Chief Legal Officer, principal accounting officer and head of corporate compliance all periodically provide reports to the Audit Committee and are responsible for identifying, evaluating and implementing risk management controls and methodologies to address any identified risks. In connection with its risk management role, our Audit Committee meets privately with representatives from our independent registered public accounting firm. The Audit Committee oversees the operation of our risk management program, including the identification of the primary risks associated with our business and periodic updates to such risks, and reports to our Board regarding these activities.
Executive session
The Board generally meets in executive session at every regularly scheduled Board meeting. These sessions are led by our independent Chairman, and involve various topics including executive officer performance and compensation, among other issues.
Communication with stockholders
Our Board values stockholder feedback, and will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Information regarding how to contact our Board is available on the Investor Relations section of our website at www.sparktx.com.

POLICIES AND PROCEDURES FOR RELATED-PERSON TRANSACTIONS
On December 29, 2014, our Board adopted written policies and procedures for the review of any transaction, arrangement or relationship in which we are a participant, the amount involved exceeds $120,000 and one of our executive officers, directors, director nominees or 5% stockholders (or their immediate family members), each of which we refer to as a “related person,” has a direct or indirect material interest.
If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a “related-person transaction,” the related person must report the proposed related-person transaction to our Chief Legal Officer. The policy calls for the proposed related-person transaction to be reviewed and, if deemed appropriate, approved by the Audit Committee of our Board. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, the committee will review and, in its discretion, may ratify the related-person transaction. The policy also permits the chair of the Audit Committee to review and, if deemed appropriate, approve proposed related-person transactions that arise between committee meetings, subject to ratification by the committee at its next meeting. Any related-person transactions that are ongoing in nature will be reviewed annually.
A related-person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, the committee will review and consider:
the related person’s interest in the related-person transaction;
the approximate dollar value of the amount involved in the related-person transaction;
the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;
whether the transaction was undertaken in the ordinary course of our business;
whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;
the purpose of, and the potential benefits to us of, the related-person transaction; and
any other information regarding the related-person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

14



The Audit Committee may approve or ratify the transaction only if the Audit Committee determines that, under all of the circumstances, the transaction is not inconsistent with our best interests. The Audit Committee may impose any conditions on the related-person transaction that it deems appropriate.
In addition to the transactions that are excluded by the instructions to the SEC’s related-person transaction disclosure rule, our Board has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related-person transactions for purposes of this policy:
 
interests arising solely from the related person’s position as an executive officer of another entity (whether or not the person is also a director of such entity) that is a participant in the transaction, where (a) the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity; (b) the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction and; (c) the amount involved in the transaction equals less than the greater of $200,000 or 5% of the annual gross revenues of the company receiving payment under the transaction; and
a transaction that is specifically contemplated by provisions of our certificate of incorporation or bylaws.
The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by the Compensation Committee in the manner specified in its charter.

PROPOSAL 2: ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION
The Board is committed to excellence in governance. As part of that commitment, and as required by Section 14A(a)(1) of the Exchange Act, the Board is providing the stockholders with an opportunity to provide an advisory vote related to the compensation of the Company’s named executive officers.
As described below under “Executive Officers and Director Compensation”, we have developed a compensation policy that is designed to attract and retain key executives responsible for our success and motivate management to enhance long-term stockholder value. We believe our compensation policy strikes an appropriate balance between the implementation of responsible, measured compensation practices and the effective provision of incentives for our named executive officers to exert their best efforts for our success.
For the reasons discussed below, the Board unanimously recommends that stockholders vote in favor of the following resolution:
“RESOLVED, that the Company’s stockholders hereby approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company’s proxy statement for the 2019 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, Summary Compensation Table and the other compensation related tables and disclosure.”
As this vote is advisory, it will not be binding upon the Board or the Compensation Committee and neither the Board nor the Compensation Committee will be required to take any action as a result of the outcome of this vote. However, the Compensation Committee will carefully consider the outcome of this vote when considering future executive compensation policies.
THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE
FOR
THE ADVISORY (NON-BINDING) RESOLUTION APPROVING THE COMPENSATION OF THE COMPANY'S NAMED EXECUTIVE OFFICERS
(PROPOSAL 2 ON YOUR PROXY CARD)

Compensation discussion and analysis

The Compensation Committee of our Board is responsible for establishing compensation policies with respect to our "named executive officers", which include our chief executive officer, chief financial officer and three other executive officers who are listed in the Summary Compensation table on page 29. Our named executive officers as of the end of our last completed fiscal year on December 31, 2018, were as follows:

Say-on-pay and transition from Emerging Growth Company status
Pursuant to Section 14A of the Exchange Act, at our 2018 Annual Meeting of Stockholders, or the 2018 Annual Meeting, our stockholders voted, in a non-binding, advisory manner, on a proposal to approve our named executive officers’ compensation, which is commonly referred to as the “say-on-pay” vote. At the 2018 Annual Meeting, 99.8% of the votes cast by stockholders on this proposal were cast in support of the compensation paid to our named executive officers. While this vote is considered to be a non-binding advisory vote, our Compensation Committee and Board value the opinions of our stockholders and seriously consider the voting results when making future executive compensation decisions.
Given the high level of support evidenced by last year’s say-on-pay vote, our Compensation Committee determined that our stockholders generally are supportive of our current executive compensation philosophy and program. As a result, our Compensation Committee decided to maintain our approach to executive compensation and declined to make significant changes to our executive compensation program. Nevertheless, our Compensation Committee and Board will continue to monitor the executive compensation program to ensure it aligns the interests of our executive officers with the interests of our stockholders and adequately addresses any stockholder concerns that may be expressed in future votes.
Consistent with the recommendation of our Board and the preference of our stockholders as reflected in the non-binding advisory vote on the frequency of future “say-on-pay” votes conducted at our 2017 Annual Meeting of Stockholders, we intend to provide for annual advisory votes on the compensation of our named executive officers.

The purpose of the following is to discuss the principles underlying our policies and decisions with respect to the compensation of our named executive officers, as well as factors considered relevant to this analysis.

Executive summary
We are a leader in the field of gene therapy, seeking to transform the lives of patients suffering from debilitating genetic diseases by developing potentially one-time, life-altering treatments. The goal of gene therapy is to overcome the effects of a malfunctioning, disease-causing gene. Gene therapies have the potential to provide long-lasting effects, dramatically and positively changing the lives of patients with conditions where no, or only palliative, therapies exist.

As described below, during 2018, we made significant progress toward our commercial, clinical development and business goals, including the following, which impacted executive compensation:
Executed U.S. launch of LUXTURNA® (voretigene neparvovec-ryzl) and shipped 75 vials during 2018 demonstrating strategic capabilities in gene therapy market development and access;
Secured and executed novel reimbursement and contracting pathways to ensure timely access for patients;
Established patient services organization to support patient access to LUXTURNA;
Received European Medicines Agency, or EMA, approval for the marketing authorization of LUXTURNA;
Progressed clinical programs for hemophilia A by collecting preliminary Phase 1/2 data, receiving breakthrough designation from FDA for SPK-8011 for hemophilia A and advancing U.S. and European Union strategy for clinical development and lifecycle management plans;
Received FDA clearance of the Investigational New Drug, or IND, application intended ultimately for non-inhibitor patients for SPK-8016, a novel, internally developed AAV gene therapy candidate;
Executed partnership with Novartis Pharma AG to commercialize LUXTURNA outside the U.S.;
Progressed early product pipeline and technology, including an expected initiation of a Phase 1/2 clinical trial for SPK-3006 for Pompe disease in 2019, continuing to advance our technology and intellectual property plan;
Advanced technical capabilities, including ensuring commercial supply of LUXTURNA in the United States and to Novartis Pharma AG, operationalizing a suspension cell culture system and developing a manufacturing capacity plan to support supply chain and pipeline demands;
Achieved operational effectiveness as a cash flow positive company in 2018; and
Sold the Rare Pediatric Disease Priority Review Voucher, or PRV, we received from FDA for LUXTURNA and continued expansion of key talent and capabilities.

The goal of our Compensation Committee is to ensure that our compensation programs are aligned with the interests of our stockholders and our business goals, while ensuring that the total compensation paid to each of our executive officers is fair, reasonable and competitive. We target our executives’ overall total compensation to be within a competitive range of the market median of similar companies in terms of industry, number of employees, lifecycle, prevalence of programs and value provided, where quantifiable. The overall objectives of our executive compensation program are as follows:

attract, retain and motivate superior executive talent;
provide incentives that reward the achievement of performance goals that directly correlate to the enhancement of stockholder value, as well as facilitate employee retention; and
align the interests of executives with those of stockholders through long-term incentives linked to individual and Company performance.

Features
Base salary
 
To attract and retain highly skilled executives.
 
Fixed component of pay to provide financial stability, based on responsibilities, experience, individual contributions and peer company data.

Typically, subject to multi-year vesting based on continued service primarily in the form of stock options and restricted stock units, the value of which depends on the performance of our common stock, in order to align executive interests with those of our stockholders over the long-term.

In addition to our direct compensation elements, the following compensation program features are designed to align our executive officers with stockholder interests and market best practices:
What We Do
 
What We Don’t Do
üMaintain commitment to pay-for-performance philosophy
 
ûAllow hedging or pledging of equity

üMaintain an industry-specific peer group for benchmarking compensation
 
ûRe-price stock options
üTarget compensation based on market norms
 
ûProvide excessive perquisites
üDeliver compensation primarily through performance-based pay
 
ûProvide tax gross-up payments for any change-of-control payments
üOffer market-competitive benefits that are consistent with our Company-wide compensation strategy
 
 
üConsult with an independent advisor on compensation levels and practices
 
 
üMaintain significant stock ownership guidelines for our non-employee directors and executive officers
 
 
Introduction of stock ownership guidelines
Effective in February 2018, our Compensation Committee approved and our Board ratified stock ownership guidelines for our non-employee directors and our executive officers. These stock ownership guidelines were established in consultation with our compensation consultant and based in part on practice by our Compensation Peer Group, as defined below, and survey data for comparable organizations. We believe these guidelines, together with our long-term incentive compensation, further demonstrate our commitment to aligning the interests of our non-employee directors and executive officers with those of our stockholders, and enable our non-employee directors and named executive officers to share in our long-term growth and success.
Our stock ownership guidelines encourage our non-employee directors and executive officers to acquire and maintain an equity interest in the Company with a value based on a multiple of their cash retainer and base salary, respectively. The following equity holdings count toward satisfying the stock ownership guidelines:

Stock directly owned and/or deferred (including vested restricted shares and shares held in retirement accounts);
Vested and unexercised stock options; and
Unvested restricted stock and restricted stock units.
We have established the following guidelines for 2018:
Role
 
Stock Ownership Guideline
Non-employee Director
 
3x annual cash retainer
Chief Executive Officer
 
3x base salary
All other executive officers
 
1x base salary
All of our executive officers and non-employee directors must be in compliance with the applicable stock ownership guidelines by the later of five years after the date of the introduction of the guidelines and the date such individual was determined to be

21



an executive officer or was appointed as a director, as applicable. Based on a preliminary analysis of current levels of base salary and annual retainers, annual restricted stock unit grant levels and our current stock price, we expect all covered individuals to be in compliance with the guidelines within five years, if not sooner.
Compensation benchmarking
In designing our executive compensation program, our Compensation Committee works directly with management and considers publicly available compensation data (public proxy and compensation survey data) for comparable life sciences companies to help guide its executive compensation decisions. Further, in 2018, our Compensation Committee continued its engagement with Willis Towers Watson as its independent compensation consultant to provide strategic advice on matters related to executive and non-employee director compensation. Although our Compensation Committee considers the advice and recommendations of Willis Towers Watson, our Compensation Committee makes its own decisions about these matters. We expect that our Compensation Committee will continue to engage an independent compensation consultant to provide strategic guidance on our executive compensation programs and to conduct further competitive benchmarking based on relevant market data.
The Compensation Committee reviewed information regarding the independence and potential conflicts of interest of Willis Towers Watson, taking into account, among other things, the factors set forth in the Nasdaq Listing Rules. Based on such review, the Compensation Committee concluded that the engagement of Willis Towers Watson did not raise any conflict of interest, and Willis Towers Watson served as an independent advisor.
In evaluating the total compensation of our named executive officers, our Compensation Committee, as advised by Willis Towers Watson, establishes a peer group of publicly traded life sciences companies that is selected considering the following criteria:

companies with a number of employees, market capitalization and stage of development comparable to us;
companies against which we compete for executive talent; and
public companies headquartered in the U.S. for which compensation data are available.
For the purpose of informing 2019 compensation benchmarking decisions, the Compensation Committee, with the advice of Willis Towers Watson, examined our existing peer group in light of the following factors:
our growth in 2018, which is anticipated to continue in 2019;
the stage of development of our product, product candidates and clinical programs; and
changes in our market capitalization.
Following this review, we modified the existing peer group by removing one company, Juno Therapeutics, since it was acquired by Celgene Corporation in March 2018. The resulting “Compensation Peer Group” was approved by our Compensation Committee and is comprised of the following 19 companies:
ACADIA Pharmaceuticals
Exelixis
Neurocrine Biosciences
Agios Pharmaceuticals
Halozyme Therapeutics
Portola Pharmaceuticals
Alnylam Pharmaceuticals
Insmed
Sage Therapeutics
Amicus Therapeutics
Intercept Pharmaceuticals
Sarepta Therapeutics
Array BioPharma
Intrexon
Tesaro
bluebird bio
Ionis Pharmaceuticals
Ultragenyx Pharmaceutical
Clovis Oncology
 
 
We believe that reviewing the compensation level and practices of the Compensation Peer Group, in addition to the compensation survey data, provide the Compensation Committee with appropriate market references for evaluating named executive officer compensation.

We utilize multiple compensation surveys in setting named executive compensation levels and evaluating leading practices, including:

Mercer’s Strategic Industry Rewards Solutions;
Radford’s Global Life Sciences Compensation Survey; and
Willis Towers Watson’s Pharmaceutical and Health Sciences Executive Compensation DataBank.

22



Other key factors in determining executive compensation
In addition to market competitive practices based on the Compensation Peer Group and compensation survey data, other performance factors we consider when determining the compensation of our named executive officers include:

achievement of U.S. commercialization goals with respect to LUXTURNA;
key research and development achievements, including advances in our clinical product candidates;
initiation and progress of clinical trials;
expansion of manufacturing and operational capabilities;
achievement of regulatory milestones;
establishment/maintenance of key strategic relationships and new business initiatives, including financings;
development of organizational capabilities and managing our growth; and
continued operations expansion.

Executive compensation evaluation process
Our Compensation Committee intends that if we achieve our corporate goals and an executive performs at the level expected, the executive should have the opportunity to receive compensation that is competitive with industry norms. Accordingly, our Compensation Committee generally targets overall compensation for executives toward the 50th percentile of the market data. However, the Compensation Committee does not apply that targeted positioning formulaically and allows for individuals to be positioned at different percentiles based on factors such as experience, historical performance, scope of duties and responsibilities and criticality to our business. At the 2018 Annual Meeting, 99.8% of the votes cast by stockholders on this proposal were cast in support of the compensation paid to our named executive officers. While this vote is considered to be a non-binding advisory vote, our Compensation Committee and Board value the opinions of our stockholders and seriously consider the voting results when making future executive compensation decisions.
In order to accomplish its objectives consistent with its philosophy for executive compensation, the Compensation Committee typically takes the following actions annually:

reviews Chief Executive Officer performance;
seeks input from our Chief Executive Officer on the performance of all other executive officers;
reviews all components of executive officer compensation, including base salary, cash bonus targets and awards, equity compensation and the estimated payout obligations under severance and change in control scenarios;
consults with Willis Towers Watson, our independent compensation consultant;
holds executive sessions, without management present; and
reviews information regarding the performance and executive compensation of other companies.
Goals for executive leadership are determined during our annual goal-setting process. We first determine goals for the Company as a whole, which helps decide goals for each executive individually. Annual corporate goals are proposed by management and approved by the Board. These corporate goals target the achievement of specific commercial, research, clinical, operational and financial objectives. The Compensation Committee determines how the various components of our annual Company goals will contribute to the overall performance evaluation.
Annual individual goals focus on contributions that facilitate the achievement of the corporate goals and are closely aligned with the corporate goals. Individual goals are proposed at the start of each year for each executive and approved by the Chief Executive Officer and, as appropriate, the Compensation Committee. The individual performance goals of each executive officer consist primarily of the key objectives and goals from our annual business plan that relate to the functional area for which the executive officer is responsible.
At the end of each year, the Compensation Committee evaluates corporate and individual performance. The Compensation Committee considers the achievement of the corporate goals and individual performance as factors in determining annual salary increases, annual bonuses and equity awards granted, if any, to our executive officers.
In assessing corporate performance, the Compensation Committee evaluates corporate performance against the approved corporate goals for the year and also evaluates other aspects of corporate performance, including achievements and progress made outside of the corporate goals. In assessing individual performance, the Compensation Committee evaluates corporate performance in the areas of each officer’s responsibility and relies on the Chief Executive Officer’s evaluation of each executive officer. The Chief Executive Officer prepares evaluations of the other executives and, in doing so, compares individual performance to the individual performance goals. The Chief Executive Officer recommends annual executive salary increases, annual equity awards and bonuses, if any, for the other executive officers, which are then reviewed and approved or

23



adjusted by the Compensation Committee. In the case of the Chief Executive Officer, the Compensation Committee conducts his individual performance evaluation.
For all executives, annual base salary increases, if any, are implemented during the first quarter of the calendar year. Annual equity awards and bonuses, if any, are granted as determined by the Compensation Committee. For 2018, equity awards and annual bonuses were awarded in the first half of 2019.

Base salary

We provide base salaries to our executive officers to compensate them with a fair and competitive base level of compensation. Our Compensation Committee typically determines base salary levels based on the executive’s responsibilities, experience, contributions, performance and, if applicable, the base salary level of the executive prior to joining the Company. In addition, our Compensation Committee reviews and considers base salaries paid by our peer group and from compensation survey data for similar positions. Our Compensation Committee believes executive salaries should be targeted within a competitive range of the market median, although it retains discretion to position executives higher or lower than market median based upon an executive’s experience, performance or other considerations.
At the beginning of 2019, our Compensation Committee approved base salary increases for each of our other named executive officers, based upon the recommendation of the Chief Executive Officer and each named executive officer’s achievement of individual goals and the comparison to the base salary of similar executives in our Compensation Peer Group and relevant compensation survey data. The table below sets forth the adjustments to base salary for each of our named executive officers:

2019 Base Salary Increases

(1) John Furey terminated his employment with the Company on January 1, 2019 
Annual cash incentive program
Our Compensation Committee aims to determine an appropriate mix of cash payments and equity incentive awards to meet short- and long-term goals and objectives. In January 2019, our Compensation Committee approved the 2018 annual incentive program payment pool and corporate modifier, including the opportunity for eligible participants to achieve incentive awards above established bonus targets based on performance relative to our 2018 primary corporate objectives.
Consistent with the Company-wide annual incentive program approved by the Compensation Committee and applicable to all employees, including our named executive officers, both a corporate performance modifier and individual performance modifier factored into the determination of each executive officer’s cash bonus award with respect to 2018.
Under the terms of our incentive plan, the corporate performance modifier is based on the degree to which corporate performance objectives have been achieved. This score is determined by the Compensation Committee and may range from 0 to 125%. The individual performance modifier is based on the degree to which individual performance objectives have been achieved, the competencies and behaviors demonstrated in achieving results and the completion of the ongoing responsibilities required by the position. The individual performance score may range from 0 to 125% and is approved by the Compensation Committee. The individual’s actual award is then calculated as follows:

Long-term incentive compensation
Our equity awards are designed to:

reflect long-term stockholder value creation over a sustained period;
align financial interests of employees with stockholders;
recognize current performance as well as the expectation of future contributions;
provide meaningful awards to support and encourage stock ownership; and
retain key employees.
The market for qualified, talented executives in our industry is highly competitive. Accordingly, we believe equity compensation is a crucial component of our competitive executive compensation package and, as such, makes up the majority of our total executive compensation package.
We typically grant equity awards to each executive officer upon commencement of employment and annually in conjunction with our review of individual performance. Beginning in 2017, equity awards for our named executive officers have consisted of a combination of time-based stock options and restricted stock units. The mix is more heavily weighted toward options than restricted stock units (70% options; 30% restricted stock units), which proportion we consider an appropriate balance of incentivizing continued stockholder value creation and promoting retention.
All equity awards to our named executive officers are approved by our Compensation Committee and, other than awards to new hires, typically are granted at our Compensation Committee’s first regularly scheduled meeting each year. No employment agreement contractually requires that a certain level of equity awards is awarded each year. Equity awards vary among our named executive officers based on their position and annual performance assessments. Each job level has a target annual grant level, which our Compensation Committee developed based on market data and input from our independent compensation consultant, Willis Towers Watson. The target annual grant level is used as a starting point in developing grant recommendations for each of the named executive officers. In addition, we review all components of compensation holistically to ensure total compensation is aligned with our overall philosophy and objectives.
All stock options that we grant have an exercise price equal to the fair market value of our stock on the grant date, so that the recipient will not earn any compensation from options unless our share price increases above the exercise price. Accordingly, this portion of compensation is at risk and is directly aligned with stockholder value creation.
In addition, equity awards granted to our executives vest over four years, which we believe provides an incentive to our executives to add value to the Company over the long term and to remain employed with the Company. All stock options have a ten-year term. Beginning in 2017, stock options and restricted stock units vest annually over a four-year period. Vesting of equity awards to employees ceases upon termination of employment and exercise rights for vested stock options at time of termination typically cease three months following termination, except in the case of death or disability. Prior to the exercise of an option or settlement of RSUs in stock, the option holder does not have any rights as a stockholder with respect to the shares subject to such option or RSU, as applicable.
In connection with the annual review of each named executive officer’s individual performance and consistent with our compensation philosophy, in January 2019, our Compensation Committee approved annual equity incentive awards for our named executive officers. The January 2019 equity awards granted to our named executive officers are set forth in the table below:

(1) John Furey terminated his employment with the Company on January 1, 2019 
We believe that equity grants provide our executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives and our stockholders. We believe these equity grants, together with our

27



stock ownership guidelines, further demonstrate our commitment to aligning the interests of our non-employee directors and executive officers with those of our stockholders and enable our non-employee directors and executive officers to share in our long-term growth and success. In addition, we believe that equity grants with a time-based vesting feature promote executive retention because this feature incentivizes our executives to remain in our employment during the vesting period. Accordingly, our Board periodically reviews the equity incentive compensation of our executive officers and, from time to time, may grant equity incentive awards to them in the form of stock options or other equity awards.
Our insider trading policy expressly prohibits short sales and derivative transactions by our employees; or other hedging or monetization transactions accomplished through the use of prepaid variable forwards, equity swaps, collars and exchange funds. In addition, our insider trading policy expressly prohibits our employees from purchasing our securities on margin, borrowing against Company securities held in a margin account or pledging our securities as collateral for a loan.
Rule 10b5-1 plans
Certain of our executive officers have previously adopted, and our other executive officers may in the future adopt, written plans, known as Rule 10b5-1 plans, in which they will contract with a broker to buy or sell shares of our common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters established by the officer when entering into the plan, without further direction from the director or officer. It also is possible that the officer could amend or terminate the plan when not in possession of material, nonpublic information. In addition, our executive officers may buy or sell additional shares outside of a Rule 10b5-1 plan when they are not in possession of material, nonpublic information.
Benefits and other compensation

401(k) retirement plan
In 2018, we maintained a 401(k) retirement plan that was intended to be a tax-qualified defined contribution plan under Section 401(k) of the Internal Revenue Code. All of our employees were eligible to participate, beginning on the first day of the month following commencement of their employment. The 401(k) plan included a salary deferral arrangement pursuant to which participants elected to reduce their current compensation by up to the statutorily prescribed limit, equal to $18,500 in 2018, and have the amount of the reduction contributed to the 401(k) plan. Participants who were at least 50 years old also could make “catch-up” contributions, which in 2018 may be up to an additional $6,000 above the statutory limit. We also made discretionary matching contributions to our 401(k) plan equal to 100% of the employee contributions up to 6% of the employee’s salary, subject to the statutorily prescribed limit, equal to $18,500 in 2018. The match immediately vested in full.

Health and welfare benefits

Our named executive officers are eligible to participate in all of our employee benefit plans, including our medical, dental, vision, life and disability insurance plans, in each case on the same basis as other employees. We believe that these health and welfare benefits help ensure that we have a productive and focused workforce through reliable and competitive health and other benefits.

Compliance with IRS Code Section 162(m)
Section 162(m) of the Internal Revenue Code of 1986, as amended, or the Code, generally disallows a tax deduction to public companies for compensation in excess of $1 million paid to each of the company’s chief executive officer and the three most highly compensated executive officers (other than the chief executive officer and chief financial officer). Pursuant to tax legislation signed into law on December 22, 2017 (the “Tax Act”), for taxable years beginning after December 31, 2017, the Section 162(m) deduction limitation is expanded so that it also applies to compensation in excess of $1 million paid to a public company’s chief financial officer.  Historically, compensation that qualified under Section 162(m) as performance-based compensation was exempt from the deduction limitation. However, subject to certain transition rules, the Tax Act eliminated the qualified performance-based compensation exception. As a result, for taxable years beginning after December 31, 2017, all compensation in excess of $1 million paid to each of the executives described above (other than certain grandfathered compensation or compensation paid pursuant to certain equity awards granted during the transition period following our initial public offering) will not be deductible by us.  
Compensation risk assessment
We believe that our executive compensation program does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs are designed to encourage our executive officers and other employees

28



to remain focused on both short-term and long-term strategic goals, in particular in connection with our pay-for-performance compensation philosophy. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

Report of the Compensation Committee on executive compensation
Our Compensation Committee has reviewed and discussed the “Compensation Discussion and Analysis” required by Item 402(b) of Regulation S-K with management. Based upon such review and discussions, our Compensation Committee recommended to our Board that such section be included in this proxy statement.

Pay ratio

The following is a reasonable estimate, prepared under applicable SEC rules, of the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of our other employees. As is permitted under the SEC rules, we used 2018 “base salary” to determine our median employee definition and not total compensation as set forth in our Summary Compensation Table. We annualized pay for those who commenced employment during 2018. Of our 349 total employees, five employees were excluded from two countries  (less than 2% of total workforce) as follows: United Kingdom - 4, Spain - 1. This resulted in an employee population of 344 that we used for purposes of our Chief Executive Officer pay ratio calculation. Using the fiscal year end date of December 31, 2018, we calculated the median base salary of this employee population. We then produced a sample of employees who were paid within a 5% range of that median base salary and selected an employee from within that group as our median employee. Because the median employee used in 2017 terminated employment, there is a different median employee used for the 2018 computation. We determined that this median employee's total compensation for 2018 was $182,200. The Chief Executive Officer's total compensation for 2018 was $3,598,572 as disclosed in the Summary Compensation Table. Therefore, our estimate of the ratio of Chief Executive Officer pay to median employee pay is 20:1. Given the different methodologies that various public companies will use to determine an estimate of their pay ratio, the ratio reported above should not be used as a basis for comparison between companies.

Employment, severance and change-in-control arrangements
We have written employment agreements with each of our named executive officers - Mr. Marrazzo, Dr. High, Mr. Webster, Mr. Faga and Mr. Furey, who terminated his employment with us on January 1, 2019. The agreements with each of our executive officers provide for at-will employment. In addition, each of our executive officers is subject to invention assignment, non-disclosure, non-competition and non-solicitation agreements through separate agreements that were executed and delivered by the executives in connection with their employment agreements.
Potential payments upon termination or change in control
Pursuant to the terms of each executive officer's employment agreement, upon execution and effectiveness of a separation agreement and release of claims, each executive officer is entitled to severance payments if his or her employment is terminated under specified circumstances.
Mr. Marrazzo
If we terminate Mr. Marrazzo's employment without cause, or if Mr. Marrazzo terminates his employment with us for good reason, each as defined in his employment agreement, Mr. Marrazzo is entitled to continue receiving his base salary and insurance benefits for a period of 18 months following the date of termination of employment, the amount of any bonus

33



determined by our Board to be payable to Mr. Marrazzo for the immediately preceding year that has not yet been paid and a payment in an amount equal to the pro rata portion of his target bonus for the fiscal year in which the termination occurs.
If, within 24 months following a change in control, as defined in Mr. Marrazzo's employment agreement, we terminate Mr. Marrazzo's employment without cause or Mr. Marrazzo terminates his employment with us for good reason, Mr. Marrazzo is entitled to continue receiving his base salary for a period of 24 months and insurance benefits for a period of 18 months following the date of termination of employment, the amount of any bonus determined by our Board to be payable to him for the immediately preceding year that has not yet been paid, a payment in an amount equal to the pro rata portion of Mr. Marrazzo's target bonus for the fiscal year in which the termination occurs and an additional payment equal to two times his target bonus for the fiscal year in which the termination occurs.
Other executive officers
If we terminate any of our other executive officers' employment without cause, or if such executive officer terminates his or her employment with us for good reason, each as defined in his or her employment agreement, such executive officer is entitled to continue receiving his or her base salary and health insurance benefits for a period of 12 months following the date of termination of employment, the amount of any bonus determined by our Board to be payable to the executive officer for the immediately preceding year that has not yet been paid and a payment in an amount equal to the pro rata portion of his or her target bonus for the fiscal year in which the termination occurs.
If, within 24 months following a change in control, as defined in such executive officer’s employment agreement, we terminate such executive officer’s employment without cause or such executive officer terminates his or her employment with us for good reason, such executive officer is entitled to continue receiving his or her base salary and health insurance benefits for a period of 18 months following the date of termination of employment, the amount of any bonus determined by our Board to be payable to the executive for the immediately preceding year that has not yet been paid, a payment in an amount equal to the pro rata portion of such executive officer’s target bonus for the fiscal year in which the termination occurs and an additional payment equal to 1.5 times his or her target bonus for the fiscal year in which the termination occurs.
Equity awards
If we terminate any of our executive officers' employment without cause, or if any such executive officer terminates his or her employment with us for good reason, the vesting periods for such named executive officer's unvested equity awards will accelerate based on the ratio of months worked by the executive during the vesting period to the number of months in the vesting period.
In addition, if there is a change in control, any unvested equity granted prior to the corporate conversion will vest as follows: (a) 50% of the unvested portion of each of our executive officers’ unvested equity awards that were outstanding at the time of the change in control will vest immediately, and (b) the remaining 50% will vest in equal quarterly installments over the following two years or, if shorter, over the remaining period of the award’s original vesting schedule; provided, however, that the new vesting schedule will not replace any more favorable vesting acceleration provision provided for in any equity award agreement governing an equity award held by such executive officer. Following a termination without cause or for good reason within 24 months of the change in control, such executive officer’s unvested equity awards that were outstanding at the time of the change in control will vest in full.
To the extent that any severance or other compensation payment to any of our executive officers pursuant to an employment agreement or any other agreement constitutes an “excess parachute payment” within the meaning of Sections 280G and 4999 of the Internal Revenue Code of 1986, as amended, then such executive officer will receive the full amount of such severance and other payments, or a reduced amount intended to avoid the application of Sections 280G and 4999, whichever provides the executive with the highest amount on an after-tax basis.
Consulting agreement with Mr. Furey
In connection with his resignation of employment from the Company on January 1, 2019, we entered into a consulting agreement with John Furey, our former Chief Operating Officer, in November 2018, pursuant to which Mr. Furey agreed to provide certain transition services and expertise to the Company, as requested, following the end of his employment. Mr. Furey's consulting agreement became effective on January 2, 2019 and terminated on June 28, 2019 (the "Consultancy Period"). In exchange for his services as a consultant, Mr. Furey received the following benefits: (i) reimbursement of all reasonable, necessary, and documented out of pocket expenses incurred or paid by Mr. Furey in connection with the consulting services; (ii) continued vesting in certain stock option and restricted stock units awards until the end of the Consultancy Period

34



("Equity Awards"); and (iii) a monthly consultancy fee of $39,166.67. Mr. Furey's agreement also provides that any acceleration provisions set forth in the Equity Awards and in Section 9(c) of our 2015 Stock Incentive Plan ("2015 Plan") are not applicable to the Equity Awards. Instead, should Mr. Furey be terminated following a Change in Control Event (as defined in the 2015 Plan), Mr. Furey will be entitled to receive all fees and vesting of the Equity Awards as if Mr. Furey had provided services to the Company for the entirety of the Consultancy Period. Mr. Furey is also bound by certain propriety information and invention assignment obligations as set forth in his consulting agreement.



35



Potential termination and change-in-control payments
Potential termination and change-in-control payments pursuant to the employment agreements assuming (i) a qualifying termination or CIC (where all outstanding equity awards were assumed, substituted or continued by the successor), occurred on December 31, 2018 and (ii) the Company experienced a CIC (where all outstanding equity awarded were assumed, substituted or continued by the successor) are set forth in the table below using our common stock price of $39.14, the closing price of our common stock on the Nasdaq Global Select Market on December 31, 2018. In addition to the amounts shown in the table below, each executive would receive payments for amounts of base salary and vacation time accrued through the date of termination and payment for any reimbursable business expenses incurred.

Upon involuntary termination or termination for Good Reason (not associated with a change in control), the Chief Executive Officer is entitled to 18 months base salary, while other named executive officers are eligible for 12 months base salary.

(3)
Upon involuntary termination or termination for Good Reason (within 24 months of a change in control), the Chief Executive Officer is eligible for 24 months base salary and two times the target annual incentive, while other named executive officers are eligible for 18 months base salary and 1.5 times the target annual incentive.
(4)
Upon involuntary termination or termination for Good Reason, all named executive officers are eligible to receive a prorata bonus for the year of termination based on the executive’s individual incentive target and hire date.
(5)
Upon termination, named executive officers are eligible for the Company to continue to pay the employer-paid portion of medical and dental benefits. The Chief Executive Officer is entitled to 18 months of the employer-paid portion of benefits for involuntary termination or termination for Good Reason (not associated with a change-in-control or within 24 months of a change-in-control). Other named executive officers are eligible for 12 months of the employer-paid portion of benefits for involuntary termination or termination for Good Reason (not associated with a change-in-control) and 18 months of the employer-paid portion of benefits for involuntary termination or termination for Good Reason (within 24 months of a change-in-control). Mr. Faga does not participate in Spark's medical and dental coverage, therefore there is no value associated with the continuation of benefits upon termination.
(6)
Upon a change-in-control, vesting for 50% of unvested equity awards will accelerate upon the change-in-control. The remaining 50% will continue to vest quarterly over a two-year period or, if shorter, over the remaining period of the award’s original vesting schedule.
(7)
Upon an involuntary termination or termination for Good Reason (absent a change-in-control), unvested equity will vest based on the proportion of the vesting schedule worked as of the date of termination.
(8)
Upon an involuntary termination or termination for Good Reason (within 24 months of a change-in-control), all unvested equity awards will vest.

Director compensation arrangements

For 2018, our non-employee directors are compensated for their services on our Board as follows:

upon appointment to the Board, directors receive a one-time stock option award of 8,000 shares and 3,000 restricted stock units;
annually, each member of the Board receives a grant of an option to purchase 4,000 shares and 1,500 restricted stock units, on the date of the annual meeting;
each non-employee director receives an annual retainer of $40,000;
the chairman of the Board receives an additional annual retainer of $30,000;
each non-employee director who serves as member of a committee of our Board receives additional compensation as follows:

37



Audit Committee - an annual retainer of $10,000; chair - an annual retainer of $20,000;
Compensation Committee - an annual retainer of $7,500; chair - an annual retainer of $15,000; and
Nominating and Corporate Governance Committee - an annual retainer of $5,000; chair - an annual retainer of $10,000; and
Science and Technology Committee - an annual retainer of $5,000; if a non-employee director chair - an annual retainer of $10,000.
Each annual retainer is payable in arrears in four equal quarterly installments on the last day of each quarter, provided that the amount of each payment will be prorated for any portion of a quarter that a director is not serving on our Board.
Each member of our Board also will be entitled to be reimbursed for reasonable travel and other expenses incurred in connection with attending meetings of the Board and any committee of the Board on which he or she serves.
Limitation of liability and indemnification
Our Restated Certificate of Incorporation limits the personal liability of directors for breach of fiduciary duty to the maximum extent permitted by the Delaware General Corporation Law, or DGCL, and provides that no director will have personal liability to us or to our stockholders for monetary damages for breach of fiduciary duty or other duty as a director. However, these provisions do not eliminate or limit the liability of any of our directors:
 
for any breach of the director’s duty of loyalty to us or our stockholders;
for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;
for voting or assenting to unlawful payments of dividends, stock repurchases or other distributions; or
for any transaction from which the director derived an improper personal benefit.
Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to such amendment or repeal. If the DGCL is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the DGCL.
In addition, our Restated Certificate of Incorporation provides that we must indemnify our directors and officers and we must advance expenses, including attorneys’ fees, to our directors and officers in connection with legal proceedings, subject to very limited exceptions.
We maintain a general liability insurance policy that covers certain liabilities of our directors and executive officers arising out of claims based on acts or omissions in their capacities as directors or executive officers. In addition, we intend to enter into indemnification agreements with each of our directors and executive officers. These indemnification agreements may require us, among other things, to indemnify each such director or executive officer for some expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by him or her in any action or proceeding arising out of his or her service as one of our directors or executive officers.
Certain of our non-employee directors may, through their relationships with their employers, be insured and/or indemnified against certain liabilities incurred in their capacity as members of our Board.
Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, or the Securities Act, may be permitted to directors, executive officers or persons controlling us, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

EQUITY INCENTIVE AND OTHER COMPENSATION PLANS
Stock option and other compensation plans
In this section we describe our 2014 stock incentive plan, as amended to date, or the 2014 plan, our 2015 stock incentive plan, or the 2015 plan, and our 2015 employee stock purchase plan. Prior to our initial public offering, we granted awards to eligible participants under the 2014 plan. Following the effectiveness of the registration statement for our initial public offering, we ceased granting awards under the 2014 plan and started granting awards to eligible participants under the 2015 plan.
2014 plan
The 2014 plan was adopted by our Board and approved by our stockholders in May 2014. The 2014 plan provides for the grant of incentive stock options, nonstatutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights and other stock-based awards. Our employees, officers, directors, consultants and advisors are eligible to receive awards under our 2014 plan; however, incentive stock options may only be granted to our employees.
The type of award granted under our 2014 plan and the terms of such award are set forth in the applicable award agreement.
Pursuant to the terms of the 2014 plan, our Board (or a committee delegated by our Board) administers the plan and, subject to any limitations in the plan, selects the recipients of awards and determines:
 
the number of shares of our common stock covered by options and the dates upon which the options become exercisable;
the type of options to be granted;
the duration of options, which may not be in excess of ten years;
the exercise price of options, which must be at least equal to the fair market value of our common stock on the date of grant; and
the number of shares of our common stock subject to, and the terms of any stock appreciation rights, restricted stock awards, restricted stock units or other stock-based awards and the terms and conditions of such awards, including conditions for repurchase, measurement price, issue price and repurchase price (though the measurement price of stock appreciation rights must be at least equal to the fair market value of our common stock on the date of grant and the duration of such awards may not be in excess of ten years).
Effect of certain changes in capitalization.
Upon the occurrence of any of a stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of our common stock other than an ordinary cash dividend, our Board shall equitably adjust:
 
the number and class of securities available under the 2014 plan;
the number and class of securities and exercise price per share of each outstanding option;
the share and per-share provisions and the measurement price of each outstanding stock appreciation right;
the number of shares subject to, and the repurchase price per share subject to, each outstanding restricted stock award; and
the share and per-share related provisions and the purchase price, if any, of each other stock-based award.
Effect of certain corporate transactions
Upon a merger or other reorganization event (as defined in our 2014 plan), our Board may, in its sole discretion, take any one or more of the following actions pursuant to the 2014 plan as to some or all outstanding awards other than restricted stock:
 
provide that all outstanding awards shall be assumed, or substantially equivalent awards shall be substituted, by the acquiring or successor corporation (or an affiliate thereof);
upon written notice to a participant, provide that all of the participant’s vested but unexercised awards will terminate immediately prior to the consummation of such reorganization event unless exercised by the participant;
provide that outstanding awards shall become exercisable, realizable or deliverable, or restrictions applicable to an award shall lapse, in whole or in part, prior to or upon such reorganization event;
in the event of a reorganization event pursuant to which holders of shares of our common stock will receive a cash payment for each share surrendered in the reorganization event, make or provide for a cash payment to the participants with respect to each award held by a participant equal to (1) the number of shares of our common stock subject to the vested portion of the award (after giving effect to any acceleration of vesting that occurs upon or immediately prior to such reorganization event) multiplied by (2) the excess, if any, of the cash payment for each share surrendered in the

39



reorganization event over the exercise, measurement or purchase price of such award and any applicable tax withholdings, in exchange for the termination of such award; and/or
provide that, in connection with a liquidation or dissolution, awards shall convert into the right to receive liquidation proceeds (if applicable, net of the exercise, measurement or purchase price thereof and any applicable tax withholdings).
Our Board does not need to take the same action with respect to all awards and may take different actions with respect to portions of the same award.
In the case of certain restricted stock units, no assumption or substitution is permitted, and the restricted stock units will instead be settled in accordance with the terms of the applicable restricted stock unit agreement.
Upon the occurrence of a reorganization event other than a liquidation or dissolution, the repurchase and other rights with respect to outstanding awards of restricted stock will continue for the benefit of the successor company and will, unless the Board may otherwise determine, apply to the cash, securities or other property into which shares of our common stock are converted or exchanged pursuant to the reorganization event. Upon the occurrence of a reorganization event involving a liquidation or dissolution, all restrictions and conditions on each outstanding restricted stock award will automatically be deemed terminated or satisfied, unless otherwise provided in the agreement evidencing the restricted stock award.
At any time, our Board may, in its sole discretion, provide that any award under the 2014 plan will become immediately exercisable in full or in part, free of some or all restrictions or conditions, or otherwise realizable in full or in part.
As of July 8, 2019, there were options to purchase 470,585 shares of our common stock outstanding under the 2014 plan, at a weighted-average exercise price of $3.89 per share, and options to purchase 1,624,569 shares of our common stock had been exercised.
Our Board may amend, suspend or terminate the 2014 plan at any time, except that stockholder approval may be required to comply with applicable law or stock market requirements.
2015 plan
Our 2015 plan, which became effective on January 30, 2015, was adopted by our Board and approved by our stockholders in January 2015. The 2015 plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock-based awards. Under the 2015 plan, the number of shares of our common stock that is reserved for issuance is the sum of: (1) 1,830,000 plus; (2) 209,519 shares reserved for issuance under the 2014 plan that remained available for grant under the 2014 plan immediately prior to the closing of our initial public offering and the number of shares of our common stock subject to outstanding awards under the 2014 plan that expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased by us at their original issuance price pursuant to a contractual repurchase right; plus (3) an annual increase, to be added on the first day of each fiscal year, beginning with the fiscal year ending December 31, 2016 and continuing until, and including, the fiscal year ending December 31, 2025, equal to the lowest of 1,724,000 shares of our common stock, 4% of the number of shares of our common stock outstanding on the first day of such fiscal year and an amount determined by our Board. As of December 31, 2018, 1,422,190 shares were available for issuance under the 2015 Plan. As of January 1, 2019, the number of shares authorized for issuance under the 2015 plan automatically increased, pursuant to the terms of the plan, by 1,510,533 shares of common stock.
Our employees, officers, directors, consultants and advisors are eligible to receive awards under the 2015 plan. Incentive stock options, however, may only be granted to our employees.
Pursuant to the terms of the 2015 plan, our Board (or a committee delegated by our Board) administer the plan and, subject to any limitations in the plan, will select the recipients of awards and determine:
 
the number of shares of our common stock covered by options and the dates upon which the options become exercisable;
the type of options to be granted;
the duration of options, which may not be in excess of ten years;
the exercise price of options, which must be at least equal to the fair market value of our common stock on the date of grant; and
the number of shares of our common stock subject to and the terms of any stock appreciation rights, restricted stock awards, restricted stock units or other stock-based awards and the terms and conditions of such awards, including conditions for repurchase, issue price and repurchase price (though the measurement price of stock appreciation rights must be at least equal to the fair market value of our common stock on the date of grant and the duration of such awards may not be in excess of ten years).

40



If our Board delegates authority to an executive officer to grant awards under the 2015 plan, the executive officer will have the power to make awards to all of our employees, except executive officers. Our Board will fix the terms of the awards to be granted by such executive officer, including the exercise price of such awards (which may include a formula by which the exercise price will be determined), and the maximum number of shares subject to awards that such executive officer may make.
As of July 8, 2019, there were options to purchase 2,810,755 shares of our common stock outstanding under the 2015 plan, at a weighted-average exercise price of $50.03 per share, and 1,342,584 options to purchase shares of our common stock had been exercised.
Effect of certain changes in capitalization
Upon the occurrence of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of our common stock other than an ordinary cash dividend, our Board shall equitably adjust:
 
the number and class of securities available under the 2015 plan;
the share counting rules under the 2015 plan;
the number and class of securities and exercise price per share of each outstanding option;
the share and per-share provisions and the measurement price of each outstanding stock appreciation right;
the number of shares subject to, and the repurchase price per share subject to, each outstanding restricted stock award; and
the share and per-share related provisions and the purchase price, if any, of each other stock-based award.

Effect of certain corporate transactions
Upon a merger or other reorganization event (as defined in our 2015 plan), our Board may, on such terms as our Board determines (except to the extent specifically provided otherwise in an applicable award agreement or other agreement between the participant and us), take any one or more of the following actions pursuant to the 2015 plan as to some or all outstanding awards, other than restricted stock awards:
 
provide that all outstanding awards shall be assumed, or substantially equivalent awards shall be substituted, by the acquiring or successor corporation (or an affiliate thereof);
upon written notice to a participant, provide that all of the participant’s unvested and/or vested but unexercised awards will terminate immediately prior to the consummation of such reorganization event unless exercised by the participant (to the extent then exercisable);
provide that outstanding awards shall become exercisable, realizable or deliverable, or restrictions applicable to an award shall lapse, in whole or in part, prior to or upon such reorganization event;
in the event of a reorganization event pursuant to which holders of shares of our common stock will receive a cash payment for each share surrendered in the reorganization event, make or provide for a cash payment to the participants with respect to each award held by a participant equal to (1) the number of shares of our common stock subject to the vested portion of the award (after giving effect to any acceleration of vesting that occurs upon or immediately prior to such reorganization event) multiplied by (2) the excess, if any, of the cash payment for each share surrendered in the reorganization event over the exercise, measurement or purchase price of such award and any applicable tax withholdings, in exchange for the termination of such award; and/or
provide that, in connection with a liquidation or dissolution, awards shall convert into the right to receive liquidation proceeds (if applicable, net of the exercise, measurement or purchase price thereof and any applicable tax withholdings).
Our Board does not need to take the same action with respect to all awards, all awards held by a participant or all awards of the same type.
In the case of restricted stock units, no assumption or substitution is permitted, and the restricted stock units will instead be settled in accordance with the terms of the applicable restricted stock unit agreement.
Upon the occurrence of a reorganization event other than a liquidation or dissolution, the repurchase and other rights with respect to outstanding restricted stock awards will continue for the benefit of the successor company and will, unless the Board may otherwise determine, apply to the cash, securities or other property into which shares of our common stock are converted or exchanged pursuant to the reorganization event. Upon the occurrence of a reorganization event involving a liquidation or dissolution, all restrictions and conditions on each outstanding restricted stock award automatically will be deemed terminated or satisfied, unless otherwise provided in the agreement evidencing the restricted stock award or any other agreement between the participant and us.

41



The 2015 plan provides that, except to the extent specifically provided to the contrary in an award agreement or any other agreement between the participant and us, immediately prior to a change in control event (as defined in our 2015 plan), the vesting schedule of each outstanding option and restricted stock award shall be accelerated in part so that 50% of the unvested portion of such award shall immediately become exercisable or free from forfeiture or repurchase, as applicable, and the remaining 50% shall vest in substantially equal quarterly installments over the following two years, or, if shorter, in accordance with the original vesting schedule set forth in the award agreement governing such award. Additionally, each such option or restricted stock award shall vest in full and become exercisable or free from forfeiture or repurchase, as applicable, if, on or prior to the second anniversary of the change in control event, the participant’s employment with the Company or the acquiring company is terminated for good reason by the participant or is terminated without cause by the Company or the acquiring corporation (as such terms are defined in the 2015 plan). However, if the acquiring corporation does not provide for the assumption or substitution of unvested options or restricted stock awards in connection with the change in control event, each such option and restricted stock award shall vest in full and become exercisable or free from forfeiture or repurchase, as applicable, immediately prior to the change in control event. Our Board may specify in an award agreement at the time of grant the effect of a change in control event on an restricted stock units, stock appreciation rights or other stock-based awards.
At any time, our Board may, in its sole discretion, provide that any award under the 2015 plan will become immediately exercisable in full or in part, free of some or all restrictions or conditions, or otherwise realizable in whole or in part as the case may be.
No award may be granted under the 2015 plan on or after January 29, 2025. Our Board may amend, suspend or terminate the 2015 plan at any time, except that stockholder approval may be required to comply with applicable law or stock market requirements.
2015 employee stock purchase plan
Our 2015 employee stock purchase plan, or the 2015 ESPP, which became effective upon the closing of our initial public offering, was adopted by our Board and approved by our stockholders in January 2015. The 2015 ESPP is administered by our Board or by a committee appointed by our Board. The 2015 ESPP initially provided participating employees with the opportunity to purchase an aggregate of 220,000 shares of our common stock. The number of shares of our common stock reserved for issuance under the 2015 ESPP automatically will increase on the first day of each fiscal year, beginning with the fiscal year ending December 31, 2016, and continuing until, and including, the fiscal year ending December 31, 2026, in an amount equal to the lowest of: (1) 440,000 shares of our common stock; (2) 1% of the total number of shares of our common stock outstanding on the first day of the applicable fiscal year; and (3) an amount determined by our Board. For the year ended December 31, 2018, we issued 30,814 shares of common stock pursuant to the 2015 ESPP. As of January 1, 2019, the number of shares authorized for issuance under the 2015 ESPP automatically increased, pursuant to the terms of the plan, by 377,633 shares of common stock.
All of our employees and employees of any of our designated subsidiaries, as defined in the 2015 ESPP, are eligible to participate in the 2015 ESPP, provided that:
 
such person is customarily employed by us or a designated subsidiary for more than 20 hours a week and for more than five months in a calendar year; and
such person was our employee or an employee of a designated subsidiary at least fifteen business days prior to the first day of the applicable offering period under the 2015 ESPP.
No employee may purchase shares of our common stock under the 2015 ESPP and any of our other employee stock purchase plans in excess of $25,000 of the fair market value of our common stock (as of the date of the option grant) in any calendar year. In addition, no employee may purchase shares of our common stock under the 2015 ESPP that would result in the employee owning 5% or more of the total combined voting power or value of our stock.
Each offering will consist of a six-month offering period during which payroll deductions will be made and held for the purchase of our common stock at the end of the offering period. Our Board may, at its discretion, choose a different period of not more than 12 months for offerings.
On the commencement date of each offering period, each eligible employee may authorize up to a maximum of 15% of his or her compensation to be deducted by us during the offering period. Each employee who continues to be a participant in the 2015 ESPP on the last business day of the offering period will be deemed to have exercised an option to purchase from us the number of whole shares of our common stock that his or her accumulated payroll deductions on such date will buy, not in excess of the maximum numbers set forth above. Under the terms of the 2015 ESPP, the purchase price shall be determined by our Board for each offering period and will be at least 85% of the applicable closing price of our common stock. If our Board does not make a determination of the purchase price, the purchase price will be 85% of the lesser of the closing price of our common stock on the first business day of the offering period or on the last business day of the offering period.

42



An employee may, for any reason, withdraw from participation in an offering prior to the end of an offering period and permanently withdraw the balance accumulated in the employee’s account. If an employee elects to discontinue his or her payroll deductions during an offering period but does not elect to withdraw his or her funds, funds previously deducted will be applied to the purchase of common stock at the end of the offering period. If a participating employee’s employment ends before the last business day of an offering period, no additional payroll deductions will be made and the balance in the employee’s account will be paid to the employee.
We will be required to make equitable adjustments to the number and class of securities available under the 2015 ESPP, the share limitations under the 2015 ESPP and the purchase price for an offering period under the 2015 ESPP to reflect stock splits, reverse stock splits, stock dividends, recapitalizations, combinations of shares, reclassifications of shares, spin-offs and other similar changes in capitalization or events or any dividends or distributions to holders of our common stock other than ordinary cash dividends.
In connection with a merger or other reorganization event (as defined in the 2015 ESPP), our Board or a committee of our Board may take any one or more of the following actions as to outstanding options to purchase shares of our common stock under the 2015 ESPP on such terms as our Board or committee determines:
 
provide that options shall be assumed, or substantially equivalent options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof);
upon written notice to employees, provide that all outstanding options will be terminated immediately prior to the consummation of such reorganization event and that all such outstanding options will become exercisable to the extent of accumulated payroll deductions as of a date specified by our Board or committee in such notice, which date shall not be less than ten days preceding the effective date of the reorganization event;
upon written notice to employees, provide that all outstanding options will be cancelled as of a date prior to the effective date of the reorganization event and that all accumulated payroll deductions will be returned to participating employees on such date;
in the event of a reorganization event under the terms of which holders of our common stock will receive upon consummation thereof a cash payment for each share surrendered in the reorganization event, change the last day of the offering period to be the date of the consummation of the reorganization event and make or provide for a cash payment to each employee equal to (1) the cash payment for each share surrendered in the reorganization event times the number of shares of our common stock that the employee’s accumulated payroll deductions as of immediately prior to the reorganization event could purchase at the applicable purchase price, where the acquisition price is treated as the fair market value of our common stock on the last day of the applicable offering period for purposes of determining the purchase price and where the number of shares that could be purchased is subject to the applicable limitations under the 2015 ESPP minus (2) the result of multiplying such number of shares by the purchase price; and/or
provide that, in connection with our liquidation or dissolution, options shall convert into the right to receive liquidation proceeds (net of the purchase price thereof).
The 2015 ESPP may be terminated at any time by our Board. Upon termination, we will refund all amounts in the accounts of participating employees.
In 2018, the Company created a sub-plan in the United Kingdom under the 2015 ESPP for the Company's employees in the United Kingdom. This sub-plan incorporates and reflects key benefits and features from the 2015 ESPP, but was specifically created for employees of the Company's UK subsidiary. The sub-plan complies with the relevant provisions of the US tax code as required by the 2015 ESPP.

RISK CONSIDERATION IN OUR COMPENSATION PROGRAM
Limits on hedging and pledging
As part of our insider trading policy, all employees, including executive officers and members of our Board, are prohibited from engaging in certain types of hedging transactions involving our securities, specifically short sales, including short sales "against the box," and purchases or sales of puts, calls or other derivative securities. Our insider trading policy also prohibits certain types of pledges of our securities by all employees, including executive officers, and members of our Board, specifically purchases of our securities on margin, borrowing against our securities held in a margin account or pledging our securities as collateral for a loan, with an exception for pledges of our securities as collateral for a loan only after certain prerequisites are met and only with the pre-approval of our Chief Financial Officer or Chief Legal Officer.
Accounting considerations
We account for equity compensation paid to our employees in accordance with ASC Topic 718, which requires us to measure and recognize compensation expense in our financial statements for all stock-based payments based on an estimate of their fair value over the service period of the award. We record cash compensation as an expense at the time the obligation is accrued.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS, MANAGEMENT AND RELATED STOCKHOLDER MATTERS
The following table sets forth information with respect to the beneficial ownership of our common stock, as of July 8, 2019, by:
each person known by us to beneficially own more than 5% of our common stock;
each of our directors;
each of our named executive officers;
and all of our executive officers and directors as a group.
The number of shares beneficially owned by each stockholder is determined under rules issued by the SEC and includes voting or investment power with respect to securities. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. Each of the stockholders listed has sole voting and investment power with respect to the shares beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable. The information is not necessarily indicative of beneficial ownership for any other purpose.
The percentage ownership calculations for beneficial ownership are based on 38,893,841shares of common stock outstanding as of July 8, 2019. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of common stock subject to options, warrants or other rights held by such person that are currently exercisable, or will become exercisable within 60 days of July 8, 2019, are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person.
 
Unless otherwise indicated, the address of all listed stockholders is 3737 Market Street, Suite 1300, Philadelphia, PA 19104.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS AND DIRECTOR INDEPENDENCE
During 2018, we have engaged in the following transactions with our directors, executive officers and holders of more than 5% of our voting securities and affiliates of our directors, executive officers and holders of more than 5% of our voting securities. We believe that all of the transactions described below were made on terms no less favorable to us than could have been obtained from unaffiliated third parties.
Ongoing collaboration with CHOP
In October 2013, we entered into a licensing agreement with CHOP, which we amended in December 2013, May 2014, December 2014 and October 2015. We also entered into a technology assignment agreement, a master research service agreement and an administrative services agreement with CHOP in October 2013, a sponsored research agreement with CHOP in October 2014 and multiple clinical trial agreements with CHOP at various times regarding the conduct of our various clinical trials. We also entered into an additional licensing agreement with CHOP in November 2015, which supplements our existing license agreement with CHOP by granting us a worldwide exclusive license, with the right to sublicense, to use and practice a provisional patent application related to the production of gene therapies. Pursuant to these agreements, we paid CHOP $5.7 million during the year ended December 31, 2018.
Steven M. Altschuler, M.D., chairman of our Board, previously served as the chief executive officer of CHOP and the CHOP Foundation.
Indemnification arrangements
Our Restated Certificate of Incorporation provides that we will indemnify our directors and officers to the fullest extent permitted by Delaware law. In addition, we have entered into indemnification agreements with each of our directors and executive officers that may be broader in scope than the specific indemnification provisions contained in the DGCL. See the “Director Compensation—Limitation of liability and indemnification” section of this Amendment for a further discussion of these arrangements.
SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
Section 16(a) of the Exchange Act requires our directors, executive officers and persons who own more than 10% of the Company's common stock to file with the SEC reports of ownership and changes in ownership of our common stock. Such persons are required by regulations of the SEC to furnish the Company with copies of all such filings. Based on our review of the reports we have received, the Company believes that all Section 16(a) filing requirements were complied with during the fiscal year ended December 31, 2018, except for one Form 4 for Mingozzi reflecting the vesting of his RSUs on June 26, 2018.

AUDIT COMMITTEE REPORT (1) 
The Audit Committee has reviewed the Company’s audited financial statements for the fiscal year ended December 31, 2018, and has discussed these statements with management and representatives of KPMG LLP, the Company’s independent registered public accounting firm. Company management is responsible for the preparation of the Company’s financial statements and for maintaining an adequate system of disclosure controls and procedures and internal control over financial reporting for that purpose. KPMG LLP is responsible for expressing an opinion on the conformity of the audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of the Company’s accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards. The Audit Committee is responsible for providing independent, objective oversight of the Company’s accounting functions and internal controls.
The Audit Committee also received from, and discussed with, members of KPMG LLP the written disclosures and other communications that the Company’s independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by AS 1301, Communication with Audit Committees, as adopted by the Public Company Accounting Oversight Board, or PCAOB. AS 1301 requires our independent registered public accounting firm to discuss with the Audit Committee, among other things, the following:
methods to account for significant unusual transactions;
the effect of significant accounting policies in controversial or emerging areas for which there is a lack of authoritative guidance or consensus;
the process used by management in formulating particularly sensitive accounting estimates and the basis for the independent registered public accounting firm’s conclusions regarding the reasonableness of those estimates; and

47



disagreements with management regarding financial accounting and reporting matters and audit procedures.
KPMG LLP also provided the Audit Committee with the written disclosures and the letter required by Rule 3526 of the PCAOB. PCAOB Rule 3526 requires independent registered public accounting firms annually to disclose in writing all relationships that in their professional opinion may reasonably be thought to bear on independence, to confirm their perceived independence and engage in a discussion of independence. The Audit Committee has reviewed this disclosure and has discussed with members of KPMG LLP their independence from the Company.
Based on its discussions with management and our independent registered public accounting firm, and its review of the representations and information provided by management and our independent registered public accounting firm, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018, for filing with the SEC.
 
Respectfully submitted by the
Audit Committee of the Board of Directors

PROPOSAL 3: RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The firm of KPMG LLP, independent registered public accounting firm, has been selected by the Audit Committee as auditors for the Company for the fiscal year ending December 31, 2019. KPMG LLP acted as the independent registered public accounting firm for the Company for the years ended December 31, 2014, December 31, 2015, December 31, 2016 and December 31, 2017. A representative of KPMG LLP is expected to be present at the Annual Meeting with the opportunity to make a statement if he or she desires and to respond to appropriate questions.
The Company’s organizational documents do not require that the stockholders ratify the selection of KPMG LLP as the Company’s independent registered public accounting firm. The Company requests such ratification as a matter of good corporate practice. A majority of the votes properly cast is required for the approval of the ratification of the selection of KPMG LLP as our independent registered public accounting firm, and brokers, bankers and other nominees have discretionary voting power on this routine matter. Abstentions and broker non-votes will have no effect on the ratification. If the stockholders do not ratify the selection, the Audit Committee will reconsider whether to retain KPMG LLP, but still may retain this firm. Even if the selection is ratified, the Audit Committee, in its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.
The Audit Committee, or a designated member thereof, pre-approves each audit and non-audit service rendered by KPMG LLP to the Company.
